THREAD GUIDE.

Application filed November 29, 1922. Serial No. 604,038.

To all whom it may concern Bt it known that I, JEssnF. M DDEN, a citizenof the United States, residing at Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inThread Guides, of which the following is a specification.

My invention relates to thread guides for textile machinery.

liy object is to provide a device of this character which can be easilythreaded and unthreaded by the operator whenever desired, but whichcannot become unthreaded by accident.

A leading feature of the invention consists of a double hookarrangementat the upper end ofthe guide, the hooks being spaced from each other anddisposed at right angles to the line of travel ofthe thread, and openingin opposite directions.

The invention consists in certain novel features of construction andarrangement of parts, as will be hereinafter described and claimed,reference being'had to the accompanying drawings, in which Fig. 1 is aperspective view showing the device complete.

Fig. 2 is a similar view, but with one of the hooks broken away to showthe other hook more clearly.

Fig. 3 is a side plan of one form of the device.

Fig. 4 is an edge view of the same; and,

Fig. 5 is a sectional view taken on the line of Fi 4.

The guide is made preferably of porcelain, and in a variety of sizes,with possible slight variations to suit the different textile machineswith which it is to be used.

Various kinds of guides have been used with textile machinery to guidethe many different kinds of threads used in weaving, out there hasalways been more or less trouble with the thread becoming unthreadedverse slot 2, which divides said end into two spaced parallel sections 3andl. Thedevice is "further provided in its upper portion with anelongated vertical opening 5 extending therethrough at right angles tosaid transverse slot and extending up wardly into the lower part of saidslot.

The spaced portions 3 and l are respectively provided with the similarhorizontal slots 6 and 7 leading out in opposite directions from. thevertical opening 5 and at the bottom of the transverse slot '2, therebyforming the upper end of the device into' two spaced parallelhooksopeningin op posite directions from each other.

The transverse slot 2 maybe flared at its I upper end if desired torender it easier to enter a thread thereinto.

' The lower end of the device has avertical opening 8 for securingthedevice "to the various makes of machines with which-it is to be used. Ascrew orfwire may be inserted into said opening, and if desired, the

connection may be made rigid by means of cement.

In operation, a thread is entered into the guide by passing a horizontalsection thereof down in the slot 2 to the bottomwill bring them into thevertical opening.

5 which forms the eye or traveling space of the guide. It will. then beimpossible for the thread to become accidentally unthreaded. no matterwhichway it pulls, or which way it rebounds in the eye,-whether up ordown or to one side or the other If it flies upwardly. it will berebounded by the upper end of the eye; and the oppositely opening hooks3 and 4 will prevent it from moving laterally out of the eye in eitherdirection. so that the thread cannot become un threaded while the deviceis in operation unless the thread breaks.

Hence it will be seen that I have provided a guide which permits thefree and easy passageof the thread there-through, and which can bequicklyv and conveniently threaded and unthreaded when desired, butwhich cannot become unthreaded by accident when in operation.

Having now described my invention,

what I claim as new and desire to by Letters Patent is 1. In a device ofthe character described,

protect an elongated body having transverse slot in its upper end toform said end into two spaced sections, the device also having anelongated opening extending through the same at right angles to saidslot, said spaced portions having individual slots leading out inopposite directions from said elongated opening, whereby to form theupper part of said member into two spaced hooks opening; at oppositesides of. the member.

'2. In a device of the character described, an elongated member havingmeans at one end for engaging and holding the same in operativeposition, said member having a transverse slot in its upper end dividingsaid end into two spaced sections, said member also having an elongatedopening leadingtheretlirough at right angles to said transverse slot andextending upwardly into said slot, said spaced sections being providedat the bottom of said transverse slot with horizontal slots leading outin opposite directions from said elongated opening, to form the upperpart of the guide into two spaced hooks opening at opposite sides of thedevice.

In testimony whereof I aflix my signature.
